Hi, I use default driver from Bootcamp 3.1 for Windows 7 x64, and my problem is, that when I run Counter Strike Source, first aprox.: 1minute is game playable around 60FPS, but after that minute I can hear starting fan rising RPM up, and FPS fall down to 20-25FPS... I'm sure there is something downclocking CPU or GPU... I'm on High Power settings... When I open HWinfo, GPU chip and memory clock are at 100MHz both! Same situation in Battlefield Heroes - game is going smooth at high settings until fan start to going higher RPM... Any ideas how to lock the GPU and CPU clock? or what should I do? I want to try driver from laptopvideo2go, help me choose the right one.
